| Abstract: | Chromatographic-grade silica gel can be converted to a form of the high-silica zeolite silicalite-1, which is suitable for use as a gas chromatographic column packing and can be used with steam as carrier gas in a suitably modified chromatograph. The material has the expected molecular sieve properties and lends itself to some novel separations based on molecular size and shape. The behaviour of lower aliphatic alcohols and chlorohydrocarbons, acetone and xylenes is reported. |
